Application filed January articulated unit type in which each unit comprises e plurality of csr bodies, the adjacent ends of two ot which are carried by a single truck., and has for an 4object the provision of side supports or bearings between the truck and the adjacent ends ot two of the bodies of a cer unit.

Another object of the invention is to proy Vide a side bearing9 for articulated. cars 'which comprises a resilient nien'ibor ndnpted to engage the car truck and adjacent ends. of two. of the bodies oit' a csr unit.

Another 'object of the invention is to provide n side bearing for an articulated cnr, comprising resilient member inountcd on e truck and loosely engaging the adjacent ends of two et the bodies oit thecnr.

A further object of the invention is to pro vide a side ben-ring for anarticnlaited car Whicii comprises a member extending be tween and at its ends engaging the adjacent ends ot .two bodiesot' the cnr and between its ends engaging an adjacent car truck.

Referring to the drawings in which like reference characters refer to like parts, l is n plan View ot' portions of the adjacent ends of two cnr bodies of the articulated cer unit; Fig. 2 is an ei'ilarged longitudinal sectional view of the saine. taken on the line 2-2 of Fig l; Fig. 3 is a cross sectional View ot the snnie, taken on the line 3-3 of Fig. 2:, Fig. is en enlarged detail side elerational view of the side bein-ine bese and Fig. is a; plan View of the sume,

Referring; non' 'in detail to the drawings the reference character l indicates an articulated car unit which con'iprises n plurality ot cer bodies Q, the adjacent end portions 3 of two of which, have been shownl in the drawings. These ends 3 are provided with body center plates l, both of which engage n, truck center plate 5 mounted on a truck `bolster ti which bolster is n part ot ag truck 7. The. center .plntesii ind are so'i'orrned that they engage with each other in such n.

Inannerns to permit the bodies 3 of the unit to move freely relative to each other and to the truck :is .the -nnit rounds a curve `or when the bodies sway troni side 'to side. @n each side-of the longitudinal center line of the bodies 53 a side bearing member 8 is pro., vided which intermediate its ,ends ,is seated e2, ieee; senin no. e033.

in a. support or base 9 secured to the truck bolster 6, y Y

The side bearing members 8 extend between the adjacent ends of adjacent bodies and each preferably comprises a spring made up of n plurality of springl plates 10 ot'varyingg lengths which are securely held togethe1',one on top of the other. through the medium of a spring band 11. The lower portion of this spring' band extends between spaced, upwardly extending lugs 12 formed in the base 9., and below1 the upper edges of such lugs, this band rests on shiins'l ar-; ranged between the lugs. stood that in some cases these shims may be omitted and the lower portion of the spring bund may rest directly upon the base 9 be-' tween the logs. The sides of the spring "bands extend into channels 14e which are toi-ined in upwardly projecting lugs 15 of the buse 9, which channelsore preferably of varying Width havingitheir greatest Widths- :lzdjeccnt their upper edges. It will be noted ti .it when the side bearing,r member is mounted in the base 9 it will be permitted to cant or roel: slightly in the direction of its length Aand yet will not become accidentally separated from the base 9. y f

iizicb the side bearing members 8 is of sutiicient length to pass across the bolster und acre le space between the ends 3 of adjacent cer bodies and at each end is provided with n shoe member 16 which is pivotally connected with the uppermost spring.

plate. 10 and its 4Lipper surece is edeptedto be engaged by :i side bearing plate or member l? secured to the underfralne of one of the cnr bodies. l

l't iwili be noted that, as the side bearing members 8 ere resilient, and loosely mounted on the truck, and thattheshoe members 16 sie pivotally mounted on the members 8, n proper bearing" between the car body and the truck is insured at all times and under all service conditions.A A

lt will be apparent to those skilled in the .art to which this invention apperteins that changes may be inodein the details of the invention without depalrting from the spirit and sco-pe of the. e pended claims.
